Mango tree named ‘R10/8’

ABSTRACT

A new mango tree named ‘R10/8’, distinguished by its tendency to dwarfing and early maturing fruit.

Genus and species: Mangifera indica.

Variety denomination: ‘R10/8’.

CROSS-REFERENCE TO RELATED APPLICATIONS

None

BACKGROUND AND SUMMARY OF THE VARIETY

The new mango tree ‘R10/8’ originated as a controlled cross of ‘Irwin’(female parent, not patented) and an unknown male parent, likely‘Kensington Pride’ (not patented). The initial cross was made atKatherine, Northern Territory, Australia, and seedlings resulting fromthe cross were planted in the same location. ‘R10/8’ was selected fromamong the seedlings for further observation due to its distinctive fruitand its tendency to dwarfing. In 2001, ‘R10/8’ was asexually propagatedby grafting at Katherine, Northern Territory, Australia and was fieldplanted the next year. ‘R10/8’ has since been observed to reproduce trueto type over successive asexually propagated generations.

‘R10/8’ is distinguishable from its parents and other known varieties bythe following characteristics:

-   -   ‘R10/8’ is poly-embryonic, as compared to ‘Hayden’ (not        patented) and ‘B74’ (“Calypso”, U.S. Plant Pat. No. 17,770)        which are mono-embryonic.    -   ‘R10/8’ is an early-maturing variety, as compared to ‘Kensington        Pride’ which matures mid-season, and ‘Honey Gold’ (not patented)        and ‘Parvin’ (not patented) which are late-maturing varieties.    -   ‘R10/8’ is a smaller tree than female parent ‘Irwin’ with        shorter internodes.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

FIG. 1 shows edible ripe fruit of the ‘R10/8’ variety;

FIG. 2 shows mature fruit of the ‘R10/8’ variety, ready to pack andtransport (about 1 month earlier than the fruit shown in FIG. 1); and,

FIG. 3 shows a tree of the ‘R10/8’ variety (planted in 2002,photographed in 2012).

The colors of the claimed variety may vary with lighting conditions.Color characteristics of the variety should therefore be determined withreference to the observations described herein, rather than from theseillustrations alone.

DETAILED BOTANICAL DESCRIPTION

The following detailed botanical description is based on observationsrecorded during the 2009 to 2012 growing seasons of three- tosix-year-old trees planted in 2006 and grown on ‘RH34’ rootstock (notpatented) at Berry Springs, Northern Territory, Australia. It should beunderstood that the characteristics described will vary somewhatdepending upon cultural practices and climatic conditions, and can varywith location and season. Quantified measurements are expressed as anaverage of measurements taken from a number of individual plants of thenew variety. The measurements of any individual plant or any group ofplants of the new variety may vary from the stated average. Colors aredescribed with reference to The Royal Horticultural Society Mini ColourChart (2007).
